Special Requirements
The devices must be installed in a protected environment in
accordance with the specific conditions on the test certificate.
Pollution degree 3 (see IEC 60664-1) must not be exceeded
for the macro environment of the device.
The devices are in accordance with the IP rating IP66 / IP67. If
the device is installed correctly, this requirement is met
by the housing as standard.
When connected to the power supply / not connected to the
power supply, the electrical circuits must not exceed
overvoltage category III / II.
For input limits or analog input limits, see the chapter titled
„Limit value tables“ on page 9.
